During the French Revolutionary Wars she spent some years on the Oporto station, where she captured many small privateers. The French captured her in 1806, early in the Napoleonic Wars. They lengthened her and she became the 17-gun privateer Duquesne. In 1807 the British recaptured her and the Royal Navy returned her to service as the 12-gun gun-brig HMS Unique. She was expended in an unsuccessful fire ship attack at Guadeloupe in 1809.
